A TTORNEY-S Patented Dec. 10, 1929 UNITED STATES PATENT OFFICE EDWIN I. E'UIPEBT, OF OWEN, WISCONSIN, ASSIGNOR TO THE MASTER PACKAGE CORPORATION, OF OWEN, WISCONSIN, A CORPORATION OF DELAWARE CONTAINER Application filed April 4,

The invention relates to containers and more particularly to a reinforced fibre or paper container.

One of the objects of the invention is to provide a cover construction wherein a fibre disk is reinforced by a metal band, which may also form the means for attaching the cover to the mouth of the container, the band being firmly fixed to the cover by upsetting the outer edge of the cover within the confines of the band.

A further object of the invention is to provide an end closure for the container wherein the mouth thereof is provided with a beaded or rounded edge by the association of the siding of the container with a metal band and the removable cover is provided with a metal band having a channel-shaped flanged portion adapted to be snapped 1 over the rounded edge of the container mouth to provide an eflicient locking connection therewith.

The invention further consists in the several features hereinafter set forth and more particular-l defined by claims at the conclusion hereof g In the drawings Fig. 1 is an elevation viewof acontainer embodying the invention, parts being broken away and parts bein shown in section;

ig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a detail sectional View showing certain modifications.

The head or cover structure, in each, instance, comprises a fibre disk 4 and a metal sheathing or band 5, preferably of thin sheet steel or other suitable sheet metal, is designed to clam ingly receive said disk and to form a more e cient interlocking connection over that of my prior application Serial No. 175,259, filed March 14, 1927.

The band 5, in each instance, has a foldedtogether portion intermediate its top and bottom edges forming a flange 6 upon which the bottom of the head seats and an upper arched or beaded portion 7 into which the outer edge portion 8 of the disk 4 is forced by upsettingsaid edge during the attachment of the band thereto, the outer edge 9 of said portion 7 also being forced down into embedded engagement with said disk. In the 1928. Serial No. 267,242.

form shown in Figs. 1 and 2 the band has .a depending channel-shaped portion 10, while in Fig. 3 the band has a plain, depending portion 11.

The method of making this cover structure consists in forming the fibre stock to a size larger than the final size, then compressing the edges of the disk to form the welt or upwardly-inclined portion 8, which is firmly wedged between the side and beaded portion 7 of the band so that the parts are securely fastened together.

The cover thus formed may be associated with different forms of fibre-bodied pails or containers but is preferably associated with fibre containers having reinforced months.

In the drawings the numeral 12 designates the siding of the container which is composed of fibre tubing. or pressed pulp formed into cylindrical or conical form and is shown as reinforced by a metal mouth band 12, formed of sheet metal, referably sheet steel, that is rolled in band orm and aflixed to the upper edge of the siding of'the container by pressing the inner edge 13 of the band into the wall of the container and bending the upper portion 14 of the band over the upper edge of the container and forcing the outer edge 15 of this head or curved portion into engagement with the sidin thereby forming a metalsheathed mouth bead.

With this construction, when the cover is placed over the mouth of the container and is pressed against the same, the inturned annular flange 16 will first be sprung out by the tapered edge of the part14 of the band 1 2 and will thereafter spring back under the bead and be securely locked thereto, thus obviating the necessity of any special cover-attaching tool.

For ease in detaching the cover a portion 17 of the in-turned flange is bent outwardly so that a crown type bottle opener tool may be started at this point and used to pry the cover out of interlocking engagement with the beaded edge of the pail mouth.

In the modified form of cover'the depend ing side portion 11 is of a diameter to snugly engage over the mouth of the container and having a cover-attaching may be secured thereto in any suitable man- I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention is:

1. Inv a container,-a cover structure comprising a fibre head disk, and a reinforcing and head-attaching band having a folded, intermediate portion forming an inwardly extending flange providing a cover and con-' tainer mouth seat and an arched portion above said flange, said disk having its outer edge portion upset into and substantially filling said arched portion, the outer edge of said arched portion having embedded engagement with said disk.

2. In a container, a cover structure comprising a fibre head disk, and areinforcing and head-attaching band having a folded intermediate portion forming an inwardly extending flange providing a cover and container mouth seat, an arched portion. above said flange, and a depending, inwardly flanged container-engaging portion, said disk having its outer edge portion upset into and substantially filling said arched portion, the outer edge of said arched portion having embedded engagement with said disk.

3. In a container, the combination with the siding, of a metal ba'nd for the mouth of the container havin a portion extending around the inner wall 0 the siding adjacent its edge and around said edge into crimped engagement with the outer side of the siding toform a head-attaching bead, a removable cover includin a fibre head and ametal band having spacef portions between which the outer edge of the head is clamped and provided with a depending portion having :1 normally in-turned flange adapted to be snapped over said head and form with said first-named flange an interlocking connection with said mouth band,

4:. In a container, the combination with the siding, of a metal band for the mouth of the container having a portion extending around the inner wall of the siding adjacent its edge and around said edge into crimped engagement with the outer side of said siding to form a head-attaching bead and having its inner edge in embedded engagement. with the inner side of said siding, a removable cover including a fibre head and a metal band having a folded, intermediate portion forming a cover and container mouth seat, an arched portion over said flange filled by the upturned edge of said head, and a de nding portion provided with an in-turne flange cooperating with said first-named flange to form a snap, interlocking connection with the beaded mouth of the container. L

In testimony whereof, I afiix my signature.
